本文通过对平板结构中柱节点在剪力与不平衡弯矩共同作用下的试验，分析国内外对中柱节点的研究资料，认为节点的破坏形态可分为弯曲破坏与剪切破坏二种形式，并给出了节点弯曲破坏与剪切破坏的计算方法，经验算，与试验结果符合情况较好。
In this paper, through experiments on the joints between the shear and unbalanced moments of the column joints in the flat plate structure, the research data on the center column joints at home and abroad are analyzed. It is believed that the failure modes of the joints can be divided into two forms: bending failure and shear failure. The calculation method of the bending failure and shear failure of the joint is given. The empirical calculation is in good agreement with the test results.
